Technology
Certification - Classe SRA
SRA (Safety and Repair Automotive) certification is a French label from the automotive industry that guarantees the quality and safety of parts and equipment. The aim of this certification is to ensure that products, such as anti-theft devices, are resistant, durable and comply with safety standards.
The label is issued by an independent organisation that evaluates products to verify their effectiveness. This lets owners and insurers know that certified products are reliable. Using SRA-certified locks helps to protect bicycles against theft and to ensure safe riding.
